ALRIGHT I WAS WORKING ON THE RIGHT SENSOR. THE COLORS OF THE WIRES DONT MATCH ANY DIAGRAMS.? ANYWAY I CHECKED THE VOLTAGE (KEY ON ENGINE OFF) ON B1, S2 WIRES AND B2, S2 WIRES. THE RESULTS WERE 1 WIRE ON BOTH SENSORS READ 10-12 VOLTS, ANOTHER READ 2-4 VOLTS. THE GROUNDS WORKED WELL OBVIOUSLY. HERE'S WHERE I FOUND A PROBLEM. B2, S2 HAS A SOLID PURPLE WIRE THAT READ 4-5 VOLTS. B1, S2 HAD A PUR/WHT STRIPE WIRE THAT READ NOTHING. I UNBOLTED AND PULLED OUT THE PCM. THEN REMOVED THE TAPE AND CORRUGATING FROM ALL WIRES. I TRACED THE PUR/WHT WIRE TO THE PCM AND TOOK A READING. STILL IT READ ZERO. I THEN TRACED THE PUR WIRE AND GOT A READING OF 4-5 VOLTS. I CHECKED THE PRONG AND WIRE INSIDE THE HARNESS. OTHER THAN A LITTLE PULL ON THE WIRE, THE PRONG WAS LOCKED IN PLACE AND MADE A GOOD CONNECTION TO THE PCM. IT LOOKS TO ME THAT THE PCM IS NOT TRANSMITTING TO B1, S2 BUT IS TO B2, S2. COULD I SPLICE THE 2 TOGETHER? B2, S2 IS LOCATED WHERE THE 2 PIPES COME TOGETHER WHILE B1, S2 IS UNDER THE ENGINE. I THINK IT WOULD WORK FINE THIS WAY AND KEEP THE LIGHT OFF. DOERS MY PCM NEED TO BE REPLACED? WHAT DO YOU THINK? LET ME KNOW. THANKS.
